Specification of Letters Patent.

Patented Oct. 1, 1912.

Application filed January 17, 1912. Serial No. 671,688.

To all whom it may concern:

Be it lmown that l, TozAnUno SUZ KI, a subject of the Emperor of Japan, residing lie. e 01 Jiheishinden, Suna-mura, county of h/linami Katsushika, Prefecture of Tokyo, Japan, have invented certain new and useful improvements in Drying ripparatus, of which the following is a spee1- lication. a

My present invention relates to drying apparatus for plants or tufty fibrous ma terials, wherein it is passed through the apparatus on suitable conveying means after having previouly been distributed thereupon, and subjected to currents of air adapted to expel moisture therefrom.

The principal objects of my invention are to provide an apparatus which will thoroughly and uniformly dry the material; to

so dispose the directmg means of the current of air that the conveying means for the materials may be successively moved through the chambers of the apparatus thus facilitating the operation, and, to direct the currents of air within the chambers to follow a path closely adjacent the materials to be treated, and to break up the strata llke currents adjacent the walls of the apparatus.

Further objects of my invention W111 be more particularly pointed out in the following detailed description.

in the drawings, forming a part of th1s specification: Figure l is a vertical longitudinal section through one of the housings of the apparatus embodying my invention.

2 is a sectional plan view through 00- acting housings of the type shown in Fig. l, embodying my invention. Fig. 3 is a transverse vertical sectional view, through the housings, as disclosed in Fig. 2. Fig. d is a view similar to Fig. 1, showing the modifications of my invention. Fig. 5 is a view similar to Egg: 2, relating to the modification shown in Fig. d. Fig. 6 is a view similar to Fig. 3, relating to the device as disclosed in Fig. 4.

Similar characters refer to similar parts throughout the several views.

The drying apparatus as disclosed in ll, 2 and 3 of the drawing, comprises two gitudinally through the housings B and C,

each including a drying chamber 1, distributing chamber 2, and an exhaust chamber 3, all separated by doors or movable partitions as will be subsequently disclosed.

The materials to be treated are supported upon suitable vehicles A which are preferably mounted upon rails 15 extending longitudinally through the housings B and C, through each of the compartments 1, 2 and 3 thereof, and at their ends, rails 16 are provided, at a lower level than rails 15, and a switching car A may be provided to trans fer the cars from the rails of housings B to the rails of housing C, or vice versa.

Referring more particularly to the housings B and C, which, are preferably identical but arranged in inverse order, access is gained to the housing by the doors 14: adjacent the exhaust chamber 3, which latter are separated from the drying chambers l by doors 8. These doors 8 are perforated as at 10, and said perforations are controlled by dampers 12, for a purpose to be subsequently described.

The distributing chamber 2 is separated from drying chamber 1 by partitions 7, which are preferably carried by doors 13 at the end of the housing, so that upon opening these doors the distributing chamber is separated into halves, and the ve hicles A may be drawn. out of thehousing at the distributing chamber end thereof.

The partitions 7 have perforations 9 which are provided, adjacent their upper margins, j with downwardly projecting deflecting plate 11 disposed in superposed spaced apart relation to each other, with each succeeding plate projecting beyond the outer, margin of the subjacent plate;

A conduit 5 is adapted to deliver air to a port 4:, opening into the distributing chamber, so disposed 'below the deflecting plate 11 that the air rising therefrom impmges said plate and is guided through the openings 9 in stratalike currents of substantially uniform density, the air traversing the chamber 1, entering chamber 3, where it finds egress through suitable stacks 6 in their equivalent. lily regulating the apertures 10 in the doors 8, the velocity of. the flow of the air in chamber 1. maytm adjusted to attain the most practical and afifcient drying of the material therein.-

lln order to break up the strata like ourrents adjacent the walls of the chamber 1 and to direct such currents to circulate adjacent the material carried by the vehicle A, ,on the ceiling Wall I provide movable de plate 17 which normally assumesa fleeting plosition due to the force of gravi pendent 5 but whic when engaged by the vehicle entering by doors'14, engages such plates.

The operation of the apparatus disclosed in Figs. 1 to 3, inclusive, 1s as follows: The materials to be treated are carried by vehicles A which are wheeled into the chamber 1, of housing B, passing through chamber 3, in succeeding relation, and the air current is distributed from chamber 2, traversing through chamber 1, deflected by plates 17 and 18, as described, and finding egress through chamber 3. The vehicle next adjacent the chamber 2 is the first to be taken from housing B and is wheeled upon switching car vA which transfers it to the tracks 15 of housing 0, whereupon it is wheeled into chamber 1 of housing C, through chamber 23,. and inasmuch as thanurrent of air in chamber 1 of housin C flows in a counter direction to that flowing. through chamber 1 of housing B, the materials are uniforml dried when they are again wheeled throug doors 13 of housing G. The vehicles A are then unloaded and reloaded, when they are in convenient proximity to again enter chamber 1 of housing B.

In connection with the device as disclosed in Figs. 4, 5 and 6, of the drawing, the same idea of directing the currents in counter direction' to each other through the drying chambers is carried out, however, the housing D- in combination with the vehicle A, provide, as it were, a plurality of heating chambers l and the cars are disposed so that they register substantially with the distributing chamber 2 and exhaust chamber 3 which are disposed. laterally of the rails 15' traversing the chamber As clearly shown in Fi -5 of the drawing, the chambers at one slde ofthe rails 15 alternate and .have disposed at the opposite side of the rails a coacting chamber, such as an exhaust chamber 3 for each distributing chamber 2' and the vehicles A are of such a length as to register substantially with the said coacting chambers. The vehicles find ingress to the chambers 1, as through doors 14 and egress therefrom as through doors 13 andthe vehicles may be transferred back to the startin point by means of switching cars A, rai s 16 and supplemental rails 20.

Air is admitted into chamber 2 by the conduit 5 and the walls of said chambers next adjacent the chamber 1' are provided with apertures 9 and the deflecting plates 11, as in the previous modification, and air finding ingress to chamber 2 through port 4. Likewise the walls of chamber 3 next adjacent chamber 1 are provided with apertures 10 and stack 6 for the purpose set forth in connection with the form disclosed in Figs. 1 to 3, inclusive, of the drawing.

In the operation of the apparatus as disclosed in Figs. 4, 5 and 6, the materials are" impinged by the air current from the deflecting chamber 2, first from one side, and then from the other side, as they are moved through the housing D.

I claim 1. In a drying apparatus, the combination with a chamber having ingress and egress means for air currents and means for conveying the materials treated therethrough, of deflecting means disposed transversely of the current flow, engaging said conveying means and the interior of the chambers, with its margin adjacent said conveying means foremost in the current flow, substantially as and for the purpose set forth.

2. In a drying apparatus the combination of a chamber having ingress and egress means for air currents, means for conveying the materials treated therethrough, of defleeting lates disposed transversely of the current ow, carried by said chamber at the interior thereof and adapted to engage said conveying means, and mechanism for holding said deflecting plates closely adjacent the said conveying means when the same is transported through said chamber, in the direction counter to that of the current flow.

3. In a drying apparatus, the combination with a drying chamber and a distributing chamber separated by a Wall having a plurality of apertures, of conveying means for gaseous fluid opening into the lower portion of said distributing chamber, and a plurality of deflecting plates disposed closely adjacent the upper margins of the said apertures therein, directed downwardly and dis posed in superposed spaced apart relation to each other over the said opening of said conveying means, each plate projecting beyond the next subjacent plate, substantially as and for the purpose set forth.

4. In a drying apparatus, the combination of two housings disposed in substantially parallel relation to each other, each housing including a distributing chamber at one end, an exhaust chamber at the other end, and a drying chamber intermediate said distributing and said exhaust chambers, the end chamber of one housing being disposed at the end of its respective housing opposite from the like chamber of the other housing, conveying vehicles for transporting the materials-to be treated through said chambers, and means disposed exterior-1y of and adjacent the ends of said housings for trans porting the vehicles of either housing to the other with the vehicles disposed to traverse said drying chambers in a direction counter to that of the current flow therethrough, substantially as and for the purpose set forth.

5. In a drying apparatus, the combination of two housings disposed in substantially parallel relation to each other each housing including a distributing chamber at one end and an exhaust chamber at the other end with a drying chamber intermediate said distributing and said exhaust chambers, the chamber of one housing disposed at the end of its respective housing opposite from the like chamber of the other housing, conveying vehicles for transporting the materials to be treated through said chambers, and means disposed exteriorly of and adjacent the ends of each of said housings for'transferring the said vehicles from one housing to the other with the vehicles disposed to traverse said drying chambers in a counter direction to that of the current flow therethrough, substantially as and for the purpose set forth. a

In testimony whereof I afiix my signature in presence of two witnesses.
